CLEVELAND — Alaska and North Dakota delegates say party officials ignored their petitions demanding a roll call vote on new party rules on Monday. Those two states would have given the platoon of rebel delegates enough signatures to require a roll-call vote on the rules — a sign of party division that party leaders wanted to avoid.

North Dakota delegates said they submitted a petition through official channels, but it was simply ignored. An Alaska delegate waved his state’s petition before the convention chairman — after hours of trying to locate the party secretary, to whom delegates were required to submit the petitions.
